If an authority of a municipality has never issued any bonds, or incurred any other debts or contractual obligations, or has paid and has been released from and discharged of all debts and bonded, contractual and other obligations, the governing body of the municipality may, after three years from the date of the certificate described in subsection (c) of section 4, or earlier if a proper resolution of the authority requests the action hereinafter described, find and declare by proper resolution that its functions can be more properly carried out by a county authority and that there is no longer any need for the authority created for the municipality to function. In such case the governing body shall issue a certificate reciting the adoption of such resolution, and shall cause such certificate to be filed with the Department of State and two duplicates thereof with the Department of Community and Economic Development. Upon such filing the authority shall cease to function, and title to any assets held by the authority at that time shall pass to the municipality. A copy of the certificate described in this section shall be admissible in any suit, action or proceeding and shall be conclusive proof that the authority has ceased to be in existence.
